The aim of the paper is the quantification of the water protection ecosystem service of the forest by the method of alternative costs based on the analysis of selected water reservoirs from the region of Central Slovakia. An alternative to providing ecosystem services in this case is the cost of drinking water treatment. Based on the analysis of water treatment costs in the time period 2011–2015 of the Málinec, Klenovec and Turček water reservoirs and the forest cover of their catchments, the dependence between forest cover and the costs of drinking water treatment is quantified. Results of the regression function confirmed the dependence between forest cover and costs of drinking water treatment. The forest water protection service is determined as a potential saving of costs for water treatment of water management companies in the existence of a certain share of forest cover of the catchment. The value of this service in the case of analysed water reservoirs is in the range from 1.67 to 8.90 €/ha/year.
